Now in three different batteries, the cost and benefits of the energy storage power stations are compared according to 500kW-8H (4000KWH) energy storage power station. See below 1 to Table 2 below.
Table 1 Three different battery storage power station parameters
The parameters of Table 1 are as follows:
The lead-carbon battery uses the discharge depth of 60% DOD, so the capacity of 4000KWH storage power station needs to be configured according to 4000kWh / 0.6 = 6667kwh;
Lithium battery uses the discharge depth of 90% DOD, and the battery capacity is configured according to 4000kWh / 0.9 = 4445kwh;
The power capacitor battery uses the discharge depth of 90% DOD, but the battery capacity has about 11.6% margin, so the battery capacity is configured in 4000kWh.
Replace the number of batteries is required, which is 1 time according to the energy storage system, and the battery cycle is 10,000 times, and the cumulative payment is 27 years; the number of lithium batteries and lead carbon cells is 3000 times, and the battery needs to be replaced 3 times.
Table 2 Investment Cost and Benefits Table of Storage Power Station
Table 2 calculates the investment cost and benefits of the storage power station with the following parameters:
The price difference between commercial peak valley is calculated according to Beijing 1.01 yuan / kWh;
The annual electricity price of the energy storage system is calculated in 365 days;
The accumulated return of the energy storage system is calculated according to the number of cycles in batteries, for 27 years.
From the above table 2, there is a conclusion as follows: 27 years in full service life.
The power capacitor battery has the lowest electrical energy storage, followed by lead carbon batteries and lithium batteries;
Power capacitor battery energy storage system accumulated total gain than lead carbon battery energy storage system;
Power capacitor battery system equipment has the lowest investment, followed by lead-carbon batteries and lithium batteries.
The initial investment of the power capacitor battery system is the highest, followed by lithium batteries and lead-carbon batteries.
4000KWH The energy storage power station built in different batteries mainly has a few differences:
1. Due to the high charge and discharge efficiency of the power capacitor battery, the configuration capacity of the power capacitor battery is minimized in the same power, and the effect of saving resources is set.
2. The price of the battery of the lead-carbon battery is the lowest, followed by a lithium battery; the power capacitor battery is the highest. The power capacitor battery is more than 5 times higher than the lead carbon battery.
3. The number of cycles of the power capacitor battery is more than 3 times the lead-carbon battery and lithium battery. Therefore, the power capacitor battery does not need to replace the battery in the 27 years of the energy storage power station, while the lead-carbon battery and the lithium battery need to replace at least 3 or more batteries.
4. The full life cycle of the power capacitor battery is much higher than the lead-carbon battery, and the lithium battery is much lower.
Based on the above advantages, the power capacitor battery will definitely be widely used in the energy storage area.
The currently used chemical energy storage power station is mainly based on lithium battery energy storage power stations and lead-carbon battery energy storage power plants. In recent years, due to the importance of the state's attention to chemical energy storage power stations, it has also exposed a series of issues, which mainly hinders the promotion of chemical energy storage power stations is that there is no battery that meets people. So the power of the power of the society, the power capacitance battery is delivered.
